Function Documentation

void SDH__attribute__::CheckCRC16 ( ) const

check the CRC value in parameter_bytes. Throw an exception if check fails

tCRCValue * CRC16 ( ) const

return a ptr to the CRC value in parameter_bytes, assuming that nb_data_bytes is correct (including the CRC bytes)

Definition at line 75 of file sdhserial.cpp.

int SDH__attribute__::GetNbBytesToSend ( ) const

return the total number of bytes to send

Definition at line 81 of file sdhserial.cpp.

std::ostream &NS_SDH operator<< ( std::ostream &  stream,
sSDHBinaryRequest const &  request 
)

helper functions to insert a human readable form of the request into stream

Definition at line 190 of file sdhserial.cpp.

std::ostream &NS_SDH operator<< ( std::ostream &  stream,
sSDHBinaryResponse const &  response 
)

helper functions to insert a human readable form of the restore into stream

Definition at line 213 of file sdhserial.cpp.

struct sSDHBinaryRequest SDH__attribute__ ( (packed)  )
SDH__attribute__::sSDHBinaryRequest ( eCommandCode  command,
double *  value,
bool  use_crc16 
)

ctor, create a request with cmd_code command and eNUMBER_OF_ELEMENTS parameter from value or no parameters if value is NULL. Add crc if use_crc16 is true and set nb_data_bytes appropriately
